Hey guys, so I'm re-wiring my lights, etc. - I was wondering how much [watts, amps, Ohms] the relay is taking from a wire connected to a new 12v power source that I created from the battery, which is being used as a trigger.

I believe it is very little.

Thanks in advance.

Your question makes no sense. If I had to guess the answers would be 2, rabbit, C.

Haha, obviously I have no idea what I'm talking about. I had my rodents in the reverse order.

If a 12v input is used to energize a relay, how much draw is it using?

I wanted to use one line directly from the battery to power 5 relays.
Would that overload it? Technically its not using much power, correct?

I'm assuming not.

I kind of went another route, so I'm not sure if my question is relevant, but I'm still curious.

I'm hoping that each relay will be fused individually.......

The setup I have is simple enough, .... hopefully, this will give you the information you need.

I have a single 6 gauge wire coming from the 12 volt battery terminal to power a fuse block.
I use 20 amp fuses (because that's what came with the lights) on the output to each relay.
I use a single 5 amp fuse on the switch side of the relay for all 4 switches.
I used 14 gauge wire throughout for wiring switches, lights, and relays.

The "energizing" circuit for the relays is the 5 amp line......

So the short answer would be, less than 5 amps.
This would apply for up to 4 pairs of lights of 100 watts or less per light.

Thanks for helping me understand a little better. I decided to go against what I originally planned.

Brad, This is all your fault anyway..
Here is a teaser..
